7 '0 a-llwhom z'tmay 0012001 '1 Be it. known that a I, SAMUEL BARUCH, a citizen of theUnited States, and. resident of New York, in the county of New York and,

Stateof Newx York, have invented certain new: and useful, Improvements in Spring; Oilers, of which the following. is a, specilication.

' This invention .is an, improved o-iler for 10 laminated springs of, the charactercommom ly employed on vehicles.

Amongxthe objects of myinvention are to provide a .device which; may be easily and quickly attachedonremoved without theiaid' of tools; which isseourelyheld without liability: of rattling,but \vithoutlocking; or binding the spring or interfering with the relative movement of the-laminations which will: reniainin-place without working lengthwise/along. the'spring; which will support theilubricantin direct contact with the edge of:.theispring,and which is neat and inconspicuous and inexpensive to manufacture.

I.:have illustrated one "embodimentlof my invention lIlrlZhB' accompanying drawings, in

Which Figal isjaiside elevation? showing thedevice applied to air-spring.

Fig. 2 is a tra-nsverse section, on the lin Fig, 3 isa perspective :view of the frame part of the adevice,.and

Figs 4 is aperspective view of the, lubrie cant container;

In the device illustrated there is provided a substantially U-shaped frame member cut from a single piece; ofsheet metal bent to form "a plate orend walllO constituting-the webflportion, and top and bottom walls 11 and 12. The top and bottom walls are prefcrab-1y non-parallel and converge in the direction of the length of the spring so that when theframe is attachedto the spring with theedges of the topand bottom walls which are nearest together toward thethinner-end of thespring, the frame may move endwise along the spring toward the thicker portion of the spring to a predetermined point where it will remain in position. Springs as ordinarily mounted on, automobiles have the thinner portion of the spring, that is the portion of fewest laminations, extending upwardly or at a higher elevation than the thicker portion having the maximum number of laminations. Therefore the converging walls will limit the movement in one direction while gravity will, prevent.

movement: of the frame; in", the; other; directlon.

The end Wall 10 serves to;hold;fina,place-;a-

lubricant container; This-is-shownzasa cup 13 extending through an aperture rlb in: the endwall 10, and having its ;innerend,open directly toward the edges of .-;thex leaves@or lam nations of the/spring; To:pleventleak-- age: of theilu bricant between ithe container and the spring the container is provided: with portion or edge, sothatrsaidedge cannot 7 directly contact withivthe springn Resilient meansis provided =fo1npressing the. container. towardthe edge of thea-vehicle spring." This resilient, means :is' shown as 7a spring'18 disposed "betweenthe end-wall-10 and the. flange: 15, andiencircling the-cona taineril3. Thespring is preferably; of sub: stantially conical type, so that itm'ayz'be pressed into the minimum space; Theiframe is held in; place on 1 the :vehicle spring: by: any suitable formof retainer,- as forzinstancega cotter pin 19 extending through'thei aper+ tures' in vthe extremities of the top and-:bottom Walls 11 andi12. These walls LIBzSPflQBCl apart to a distance slightly greater than the thickness of .thevehicle, spring so that the laminations may separate slightly during the action ofztherspring.

It will be noted that-thespring l8gholds ,all of: the parts-inposition: andriagainstirattling, as well as pressing the gasket or washer to prevent escape of the lubricant except between the laminations. The lubricant being in direct contact with the edges of the laminations can Work in between them, and Will thoroughly lubricate the parts.

To remove the device it is merely necessary to press the end wall 10 toward the spring which will free the cotter pin from the opposite edge of the spring and permit of its removal. With the parts removed from the vehicle spring the container may be easily refilled with oil, grease or other desired lubricant. The spring 18 is concealed from view and protected by the plate 10, and as the walls of the frame substantially follow the top, bottom and edge surfaces of the vehicle spring the device is inconspicuous.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A lubricating device for laminated springs, including a lubricant container having an open end and a peripheral flange, an annular gasket engaging with the face of said flange, and a frame having an opening receiving said container but smaller than said flange.

'2. A lubricating device for laminated springs including a frame encircling the spring, a lubricant container having guided movement in respect to said frame and toward and from the edge of the spring, and resilient means disposed between said frame and said container.

3. A lubricating device for laminated springs, including a frame adapted to encircle the spring and having a perforated plate portion, and a lubricant container having a portion guided therein and movable inrespect thereto toward and from the edge of the-spring.

4. A lubricating device for laminated springs, including a frame adapted to encircle the spring plate portion, a lubricant container having a portion guided therein and movable in respect thereto toward and from the edge of the spring, and resilient means tending to hold said frame and container against relative movement.

5. A lubricating device for laminated springs, including a U-shaped frame member having a web portion disposed opposite to but spaced from the edges of the lamina tions, and a lubricant container between said edges and said web, and having a portion projecting through said web portion.

6. A lubricating device for laminated springs, including a U-shaped frame member having a web portion disposed opposite to but spaced from the edges of the laminations, a lubricant container between said and having a perforated edges and said web, and a spring disposed between said web portion and said container for holding said container against the edges of the laminations.

7. A lubricating device for laminated springs, including a U-shaped frame member having a web portion disposed opposite to but spaced from the edges of the laminations, a lubricant container between said edges and said web, and a spring for holding said container against the edges of the laminations, said last mentioned spring encircling said container.

8. A lubricating device for laminated springs, including a U-shaped frame member having a web portion disposed opposite to but spaced from the edges of the laminations, a lubricant container between said edges and said web, and a spring for holding said container against the edges of the laininations, said last mentioned spring encircling said container and disposed between said web portion and said container.

9. A lubricating device for laminated springs including a lubricant container having an open end and a peripheral flange, an annular gasket engaging with the face of saidflange, and means engaging with said container for forcing said gasket against the edge of the spring to permit direct contact of the lubricant through the center opening of the gasket.

10. A lubricating device for laminated springs including a lubricant container having an open end and a peripheral flange, an annular gasket engaging with the face of said flange, and means engaging with said container for forcing said gasket against the edge of the spring to permit direct contact of the lubricant through the center opening of the gasket, said means including a frame member having an aperture receiving said container but smaller than said flange.

11. A lubricating device for laminated springs, including a lubricant container having an open end and a peripheral flange, an annular gasket engaging with the face of said flange, a frame having an opening receiving said container but smaller than said flange, and a spring encircling said container between said frame and said flange.
